Specification of Letters Patent.

Application filed January 8, 1920. Serial No. 350,154.

T 0 all whom it may concern:

Be it known that I, HANNIBAL A. KUNITZ, born in Tunis, of a German father and French mother, and not positively knowing ,of what Citizenship 1 am, but having forof burners wherein the atomization of fuel,

occurs outside the burner itself. While the invention is capable of general application, it finds one advantageous use as a burner for liquid fuel, such as oil, which is atomized by mingling with a suitable fluid, such as steam or air, for example.

The object of the invention is to provide a burner built up of two members, such as a body and cap, with removable plates therebetween which cooperate with each other and the cap and body to form the nozzles of the burner.

According to this object, the removable platescontrol the thickness and width of the nozzles as well as the angle of the mouth of the nozzle, while the body and cap have no effect on the characteristics of the nozzles. Thus, the body and cap maybe standardized and used under all conditions while the removable plates may be changed or other plates substituted, to provide just the desired characteristics to meet the varying conditions of each burner installation, as encountered.

Another object of the invention is to provide a burner, comprising, a body and cap between which may be clamped a plurality of plates so arranged as to provide a plurality of nozzles for fuel and the ,atomizing medium.

Another object of the invention is to provide a burner made up of thin plates or laminations, which are clamped between a cap and body, and to build up the burner by the use of a series of each of two types of United States of America, have laminations. One series consists of nozzle forming members and the other of blank laminations and the blanks and nozzle form- Patented Apr. 5, 1921.

ing laminations are alternated to form the burner.

Another object of the invention is to provide, in a burnerof thetype described, passages for the fuel and atomizing medium and a series of similar nozzle plates, each nozzleplate being reversible and having a recess which may register with either of said passages, but not with both.

Other objects and advantages will appear in the following description and in the illustrative embodiment of the invention in the accompanying drawings, in which:

Figure 1 is a top plan view of a burner embodying the invention;

Fig. 2 is a front elevational view thereof;

Fig. 8 is a sectional plan view taken on the line 33 of Fig. 2; and

Figs. 4 and 5 are plan views showing the nozzle forming and blank plates or laminations, respectively of the burner.

Referring to these drawings; the burner comprises a body 10, a cap 11, a sense of removable plates or lamlnations between the cap and body, and suitable means, as bolts- 12 for example, for removably securing these members together. The cap and body may be formed as desired. The cap 11 has no passages other than those for the retaining bolts 12 and requires no special description. The body 10, however, has two passages 13 and 1A, in addition to those for bolts 12, which constitute the inlets for fuel, such as oil for example, and the atomizing medium, such as steam or air for example. The passsages 13 and 14 lead to the top face 15 of body 10 and the faces 15 and 16 are flat plane surfaces,'between which the removable plates or laminations are clamped. It is not 3 holes 13 and 14, so as the remaining portion plates 17 are made 19 therethrough to register with the bolt holes in the cap and body and to receive the bolts 12. Aside from such holes the blank plate 18 has two holes 20 and 21 therethrough which are so located as to register with the inlet passages 13 and 14:, the plate 1 being reversible so that either of the holes 7 may register with either of the passages.

The nozzle-forming plate 17, however, has but a single hole 22 therethrough and such hole is so located that it can register with either of theinlet passages 13 or 14 according to which of its faces is uppermost. The platec17 is also provided with a'recess 23 therethrough, which extends from the front edge of the plate inwardly to a position such that it may communicate with. either of the inlet passages 13 or 141- according to which face is uppermost. The. plate 17 is made reversible by locating the outer or nozzle end of recess 23 centrally between the two outer bolt holes 19 and centrally between the hole 22 and the inner portion of the recess. of the recess diverging to connect these two portions. The two outer bolts 19thus function as means for locating the plates relatively to the cap and body and while they also have a function as retaining means, the firstfunction is the important one for otherwise provided for if desired. 1

While preferably the nozzle forming reversible, since the one plate can then serve as the nozzle-forming member for either the fuelor the atomizing fluid, the invention, as to certain features, is independent of this arrangement. F or example, it is sometimes desired to have one nozzle wider than the other and possibly of somewhat different shape. Thus, as indicated in Figs. 1' and 2, the nozzle exit 24 of the lower plate 17 which exit is intended for steam, may be somewhat smaller than the nozzle exit 25 of the plate 17 next above it, which exit is intended for fuel. Under such conditions the reversibility of the nozzle-forming plates is not so important although it is nevertheless desirable.

In assembling the burner, a plate 17 is slipped over the bolts 12 and laid upon the face 15 of the burner-with the inner end of its recess 23 communicating with one of the inlet passages,-for example the passage 13. Thehole 22 in such plate then registers with the other passage, as 14. Then a blank plate 18 is applied on top of the plate 17 and its holes 20 and 21 line up with the topermit passages of fuel and atomizing fluid therethrough. A second plate 17 is then applied, but reversely of the first plate 17, so that the inner end of its recess 23 communicates with the passage 14 and the hole 22 registers with the passage 13. If only two nozzles,one for fuel and one for atomizing fluid,--are the retaining may be 1 larly controlled.

desired, the cap 11 is then applied, which blanks ofl both the recess 23 and hole 22 in the plate. If other nozzles are desired, as illustrated, a second blank plate 18 is applied andthe described operations are repeated. V

The operation of the burner will now be described assuming that fuel, as oil, is supplied to the passage 14: and an atomizing medium, as steam, is supplied to the passage 13. The fuel travels upwardly from the passage 14 and through the 'hole 22 in the lower plate 17 the hole 21 in the blank plate 18, and thence into the recess 23. This recess is closed off from above and below by the adjacent blank plates'18 so that a pas sage is provided through which the fuel may pass to and be emitted from the front of the burner. .In case a second fuel nozzle is provided, some of the fuel will continue on through the second blank plate 18, the third plate 17 and the third blank plate 18 into the recess 23 of the upper plate 17 which recess is closed at the bottom by the .upwardly through the first blank plate 18. the second plate 17, and the second blank plate into the recess 23 of the third plate 17. The fuel and the atomizing medium travel outwardly through their respective recesses 23 and are emitted in parallel planes, the fuel jet being preferably disposed above the jet of atomizing fluid so that the former falls into the latter and is atomized thereby.

An important feature of the described construction is that the cap and body, the relatively expensive elements of the burner,may be I standardized. That is, only one style of cap and body need be manufactured and the varying conditions of each installation may be met by varying the plates, which are relatively inexpensive to manufacture and may readily be produced by punching operations, if desired. With only the two types of plates illustrated, a burner having as many jets as desired may be produced and the relative arrangement of these jets may be varied as desired. One is not limited to the alternate arrangement of fuel and steam jets described, but can readily provide more jets for fuel than for steam or vice versa or can arrange the steam jets above the fuel jets, if desired. The conthat by substituting one for another the height of the nozzle opening may be varied. The spacing of adjacent jets may be simi- Moreover, plates having recesses 23 of di erent widths andeven different shapes may be provided. In short,

plates and may be readily varied as desired burner are readily accessible for inspection H or cleaning and access to theinteriorof the burner may be had without disturbing the piping, since there are no pipe connections to the cap 11, the inlets for both fuel and they atomizing medium being in the body, which is considered important.
